[0001] This disclosure relates to, but is not limited to, the field of wireless communication technology, and particularly to a wireless communication method, apparatus, communication device, and storage medium. Background Technology
[0002] Fifth generation mobile communication network (5G, 5 th Release 16 (R16) of Generation Mobile Networks (GMO) technology introduced various terminal positioning technologies, all of which can achieve terminal positioning.

After obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration.
[0003] In related technologies, the terminal has a long delay in acquiring the Positioning Reference Signal (PRS) configuration, resulting in a long positioning time. This prolonged positioning time leads to a poor user experience. Summary of the Invention

[0008] According to a second aspect of the present disclosure, a method for wireless communication is provided, wherein the method is applied to a terminal, the method comprising:
[0009] Receive indication information sent by the communication node;
[0010] The indication information is used to enable the terminal to determine the sending operation of the on-demand positioning reference signal (PRS) request.
[0011] According to a third aspect of the present disclosure, a wireless communication apparatus is provided, wherein the apparatus is applied to a communication node, the apparatus including a first transmitting module, wherein...

[0015] The receiving module is configured to receive indication information sent by the communication node;
[0016] The indication information is used to enable the terminal to determine the sending operation of the on-demand positioning reference signal (PRS) request.
[0017] According to a fifth aspect of the present disclosure, a communication device is provided, the communication device comprising:
[0018] processor;
[0019] Memory used to store the processor's executable instructions;
[0020] The processor is configured to implement the method described in any embodiment of this disclosure when running the executable instructions.
[0021] According to a sixth aspect of the present disclosure, a computer storage medium is provided, the computer storage medium storing a computer executable program, which, when executed by a processor, implements the methods described in any embodiment of the present disclosure.
[0022] In this embodiment, an indication message is sent to the terminal; wherein the indication message is used to enable the terminal to determine whether to send an on-demand location reference signal (PRS) request. In this way, the terminal can determine whether to send the on-demand location reference signal (PRS) based on the received indication message. Compared to sending the on-demand location reference signal (PRS) request without the indication message, this reduces the likelihood of failure when the peer cannot provide a location reference signal (PRS) configuration, thereby reducing the latency in obtaining the location reference signal (PRS) configuration, reducing the time spent locating the terminal, enabling rapid terminal location, and improving the user experience.

[0045] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several user equipment 110 and several base stations 120.
[0046] User equipment 110 can be a device that provides voice and / or data connectivity to a user. User equipment 110 can communicate with one or more core networks via a Radio Access Network (RAN). User equipment 110 can be an Internet of Things (IoT) user equipment, such as sensor devices, mobile phones (or "cellular" phones), and computers with IoT user equipment capabilities. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device.

[0047] Base station 120 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system; or it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network).
[0048] The base station 120 can be an evolved NB (eNB) used in a 4G system. Alternatively, the base station 120 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the base station 120 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the base station 120.
[0049] Base station 120 and user equipment 110 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0051] Here, the user equipment mentioned above can be considered as the terminal equipment in the following embodiments.
[0052] In some embodiments, the wireless communication system described above may further include a network management device 130.
[0053] Several base stations 120 are connected to network management device 130. Network management device 130 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 130 is not limited in this embodiment.
[0054] To better understand the technical solutions described in any embodiment of this disclosure, the application scenarios of terminal positioning will first be explained.
[0055] In one embodiment, the terminal needs to receive PRS based on the PRS configuration.
[0056] In some embodiments, PRS configuration includes PRS configuration parameters such as PRS period, bandwidth, and / or style.
[0057] In one embodiment, the base station sends the PRS configuration to the LMF. The LMF then sends the PRS configuration to the terminal.
[0058] In one embodiment, see Figure 2 The LMF requests the Observed Time Difference of Arrival (OTDOA) information from the base station via New Radio Positioning Protocol A (NRPPa) messages.
[0059] In one embodiment, after receiving a request, the base station sends a response message to the LMF via an NRPPa message, which includes the PRS configuration.
[0060] In one embodiment, see Figure 3 When the LMF receives the PRS configuration, it sends the PRS configuration to the terminal via an LPP message.
[0061] In one embodiment, after the LMF receives the PRS configuration, the LMF sends a positioning system message to the base station, wherein the positioning system message contains the PRS configuration information.
[0062] In some embodiments, PRS parameters are configured for the base station through Operation Administration and Maintenance (OAM). This PRS configuration is semi-static and is a cell-level parameter configuration.
[0063] In this configuration method, the PRS parameters cannot be changed dynamically, and different PRS parameters cannot be configured for different terminals. Therefore, the PRS configuration cannot meet the positioning requirements of different terminals.
[0064] In one embodiment, a request-based PRS configuration approach is introduced, where the PRS configuration is obtained by sending a request.
[0065] In some embodiments, the method of request-based PRS configuration includes:
[0066] The terminal sends an on-demand PRS request to the base station;
[0067] or,
[0068] The terminal sends an on-demand PRS request to the LMF;
[0069] or,
[0070] LMF sends on-demand PRS requests to the base station.
[0071] In one embodiment, when locating a terminal, multiple Transmission Reception Points (TRPs) are needed for terminal location. Therefore, it may be necessary for the base stations corresponding to neighboring cells of the cell where the terminal is located to also participate in the terminal location.
[0072] In one embodiment, when a terminal sends an on-demand PRS request to the serving base station corresponding to the serving cell, if the serving base station confirms that the terminal's neighboring base stations are also needed to participate in the terminal's positioning, the serving base station can obtain the PRS configuration of the neighboring base stations through the interface between base stations, or obtain the PRS configuration of the neighboring base stations through the LMF.
[0073] In one embodiment, the base station sends a PRS configuration requested by the terminal to the terminal, wherein the PRS configuration includes the PRS configurations of the serving base station and neighboring base stations.
[0074] However, this process has a long delay and may require the Xn interface between base stations to exchange information. Therefore, when terminal positioning requires the participation of both the serving base station and neighboring base stations, the method of the terminal sending on-demand PRS requests to the base station is not effective and may even lead to failure in obtaining PRS configuration.
[0075] In one embodiment, if only the serving base station is involved in locating the terminal (i.e., the serving base station includes multiple TRPs), then the serving base station can determine the PRS configuration. After receiving the on-demand PRS request from the terminal, the serving base station can promptly send the PRS configuration to the terminal, reducing location latency.
[0076] In one embodiment, to better meet the needs of location services, the terminal sends a request to the base station or LMF to obtain a PRS configuration that meets the requirements of the location services. Here, this request is an on-demand PRS request. That is, the terminal sends an on-demand PRS request to the base station or LMF, and the base station and / or LMF provide the PRS configuration to the terminal according to the terminal's request. After obtaining the PRS configuration, the terminal receives the PRS based on the PRS configuration.
[0077] In related technologies, if a terminal sends an on-demand PRS request to a base station, depending on the base station's deployment scenario, the delay in obtaining the required PRS configuration may be long, resulting in prolonged positioning time and a poor user experience. Therefore, indication information can be introduced to indicate whether the base station supports the terminal sending on-demand PRS requests.
[0078] like Figure 4 As shown, this embodiment provides a wireless communication method, which is applied to a communication node. The method includes:
[0079] Step 41: Send instruction information to the terminal;
[0080] The indication information is used by the terminal to determine the sending operation of the on-demand PRS request.
[0081] In some embodiments, the terminal may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a roadside unit (RSU), a smart home terminal, and an industrial sensing device.
[0082] In one embodiment, the communication node can be a base station.
[0083] This base station is an interface device for terminals to access the network.
[0084] In some embodiments, the base station can be various types of base stations, such as a base station for a third-generation mobile communication (3G) network, a base station for a fourth-generation mobile communication (4G) network, a base station for a fifth-generation mobile communication (5G) network, or other evolved base stations.
[0085] In one embodiment, the communication node can be a functional network element in the core network.
[0086] Here, the functional network element can be the Access and Mobility Management Function (AMF), the Session Management Function (SMF), or the User Plane Function (UPF), etc.
[0087] In one embodiment, the communication node is an LMF.
[0088] In one embodiment, when locating terminal A, base station B sends a Reference Signal Request (PRS) to terminal A. Upon receiving the PRS, terminal A measures it, for example, by measuring the Reference Signal Time Difference (RSTD). Based on the measurement results, the distance to terminal A is determined.
[0089] Thus, based on the RSTD measured by terminal A, base station B can locate terminal A.
[0090] In one embodiment, the terminal needs to receive the PRS based on the PRS configuration. Therefore, the terminal needs to obtain the PRS configuration before receiving the PRS.
[0091] In some embodiments, the PRS configuration includes positioning reference signal (PRS) parameters such as period, bandwidth, and / or pattern.
[0092] In one embodiment, the terminal obtains the PRS configuration from the base station.
[0093] In one embodiment, the terminal sends an on-demand PRS request to the base station to obtain the PRS configuration. The terminal then receives the PRS configuration sent by the base station in response to the on-demand PRS request.
[0094] In one embodiment, in response to the terminal needing to receive PRS, the terminal sends an on-demand PRS request to the base station to obtain PRS configuration.
[0095] In one embodiment, in response to the launch of a location application for locating the terminal, the terminal sends an on-demand PRS request to the base station to obtain PRS configuration.
[0096] In one embodiment, in response to the terminal establishing an RRC connection with the base station, the terminal sends an on-demand PRS request to the base station to obtain the PRS configuration.
[0097] In one embodiment, in response to the base station receiving an on-demand PRS request from the terminal, an indication message is sent to the terminal.
[0098] In one embodiment, in response to the establishment of an RRC connection between the base station and the terminal, an indication message is sent to the terminal.
[0099] In one embodiment, the base station may periodically send indication information to the terminal.
[0100] In one embodiment, the instruction information may instruct the base station to support the terminal in sending on-demand PRS requests to the base station.
[0101] In one embodiment, in response to a base station supporting a terminal sending an on-demand PRS request to the base station, the base station can determine the PRS configuration based on the on-demand PRS request sent by the terminal.
[0102] In one embodiment, determining the sending operation of an on-demand PRS request can be either that the terminal determines to send an on-demand PRS request to the base station or that the terminal determines not to send an on-demand PRS request to the base station.
[0103] In one embodiment, multiple TRPs are required to locate the terminal. Therefore, it may be necessary for the base stations corresponding to neighboring cells of the serving cell where the terminal is located to also participate in the terminal's location.
[0104] In one embodiment, the serving base station in response to the terminal includes multiple TRPs, the base station is able to determine the PRS configuration, and the indication information can instruct the base station to support the terminal in sending on-demand PRS requests to the base station.
[0105] In one embodiment, after receiving an instruction from the base station to support the terminal in sending an on-demand PRS request to the base station, the terminal can send an on-demand PRS request to the base station.
[0106] In one embodiment, after receiving an instruction from the base station to support the terminal in sending an on-demand PRS request to the base station, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration.
[0107] In one embodiment, the pre-defined PRS configuration can be the current PRS configuration.
[0108] In one embodiment, in response to a failure to meet positioning requirements, the terminal sends an on-demand PRS request to the base station.
[0109] In one embodiment, in response to the predetermined PRS configuration not meeting the positioning requirements, the terminal sends an on-demand PRS request to the base station.
[0110] In one embodiment, failure to meet the positioning requirement may be due to the current base station not sending a PRS and / or the terminal lacking a PRS configuration available for receiving PRS. In one embodiment, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration, including:
[0111] In response to a PRS configuration that meets the requirements of the pre-defined PRS configuration, the terminal does not send an on-demand PRS request to the base station.
[0112] And / or,
[0113] In response to a PRS configuration that does not meet the required requirements, the terminal sends an on-demand PRS request to the base station.
[0114] In one embodiment, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0115] In one embodiment, in response to the base station not supporting the terminal sending on-demand PRS requests to the base station, the base station cannot determine the PRS configuration based on the on-demand PRS requests sent by the terminal.
[0116] In one embodiment, in response to the fact that the number of TRPs included in the serving base station of the terminal is less than the threshold number of TRPs required for positioning, neighboring base stations and the serving base station need to work together to locate the terminal.
[0117] In one embodiment, the serving base station needs to exchange information through the Xn interface between base stations to obtain the PRS configuration from neighboring base stations. In this case, the latency will be very long.
[0118] In one embodiment, in response to a base station needing to obtain PRS configuration from a neighboring base station, and the base station being unable to determine the PRS configuration on its own, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0119] In one embodiment, in response to the base station not supporting the terminal sending on-demand PRS requests to the base station, the terminal does not send on-demand PRS requests to the base station.
[0120] In one embodiment, in response to the base station not supporting the terminal sending an on-demand PRS request to the base station, the terminal sends an on-demand PRS request to the LMF and obtains the PRS configuration from the LMF.
[0121] In one embodiment, after receiving an indication that the base station does not support the terminal sending on-demand PRS requests to the base station, the terminal determines whether to send on-demand PRS requests to the LMF based on a predetermined PRS configuration.
[0122] In one embodiment, determining the sending operation of the on-demand PRS request can be either that the terminal determines to send the on-demand PRS request to the LMF or that the terminal determines not to send the on-demand PRS request to the LMF.
[0123] In one embodiment, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration, including:
[0124] In response to a PRS configuration that meets the requirements of the pre-defined PRS configuration, the terminal does not send an on-demand PRS request to the LMF.
[0125] And / or,
[0126] In response to a PRS configuration that does not meet the required requirements, the terminal sends an on-demand PRS request to the LMF.
[0127] In one embodiment, the base station sends PRS configuration to the terminal via RRC messages.
[0128] In one embodiment, the LMF sends the PRS configuration to the terminal via an LPP message.
[0129] In one embodiment, the terminal can determine whether to send on-demand PRS based on the received indication information. Compared with sending on-demand PRS requests without indication information, this can reduce the possibility of failure when sending on-demand PRS to obtain PRS configuration if the peer cannot provide PRS configuration. This reduces the latency of obtaining PRS configuration, reduces the time for locating the terminal, enables rapid location of the terminal, and improves the user experience.
[0130] In one embodiment, the indication information includes one of the following:
[0131] The first piece of information instructs the base station to support the terminal in sending on-demand PRS requests to the base station.
[0132] The second piece of information indicates that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0133] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0134] like Figure 5 As shown, this embodiment provides a wireless communication method, which is applied to a base station. The method includes:
[0135] Step 51: Send a system message carrying instruction information to the terminal;
[0136] or,
[0137] During random access, an MSG2 carrying indication information is sent to the terminal;
[0138] or,
[0139] During random access, an MSG4 carrying indication information is sent to the terminal;
[0140] or,
[0141] Send an RRC message carrying indication information to the terminal;
[0142] or,
[0143] Send a MAC message carrying indication information to the terminal;
[0144] or,
[0145] Send a DCI message carrying instruction information to the terminal.
[0146] In one embodiment, the system message may be SIB1 or the location SIB.
[0147] In this way, the instruction information can be carried in system messages, second messages, fourth messages, RRC messages, MAC messages, or DCI messages, improving the message compatibility of the above messages.
[0148] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0149] like Figure 6 As shown, this embodiment provides a wireless communication method, which is applied to a base station. The method includes:
[0150] Step 61: In response to receiving the on-demand PRS request sent by the terminal to the base station, the base station cannot provide the PRS configuration requested by the terminal, and sends the second information to the terminal in response to the on-demand PRS request.
[0151] In one embodiment, in response to the fact that the number of TRPs included in the serving base station of the terminal is less than the threshold number of TRPs required for positioning, neighboring base stations need to work together with the serving base station to locate the terminal.
[0152] In one embodiment, the serving base station needs to exchange information through the Xn interface between base stations to obtain the PRS configuration from neighboring base stations. In this case, the latency will be very long.
[0153] In one embodiment, in response to a base station needing to obtain PRS configuration from a neighboring base station, and the base station being unable to provide PRS configuration on its own, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0154] In one embodiment, after receiving the on-demand PRS request sent by the receiving terminal to the base station, the receiving terminal sends a second message to the receiving terminal indicating that the base station does not support the receiving terminal sending on-demand PRS requests to the base station.
[0155] In one embodiment, in response to the base station having the ability to determine the PRS configuration requested by the on-demand PRS request (i.e., the base station can determine the PRS configuration individually) but the base station cannot meet the needs of multiple terminals requesting multiple different PRS configurations, a second message is sent for the on-demand PRS request.
[0156] For example, if multiple terminals simultaneously send on-demand PRS requests to the base station, and the PRS configurations requested in each PRS request are different, the base station cannot simultaneously satisfy all the on-demand PRS requests. Therefore, it can only send a second message to the terminals for each on-demand PRS request. Here, indication information can be sent using RRC, MAC, or DCI instead of system messages.
[0157] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0158] like Figure 7 As shown, this embodiment provides a wireless communication method, which is applied to LMF. The method includes:
[0159] Step 71: Send an LPP location information request message carrying indication information to the terminal;
[0160] or,
[0161] Send an LPP auxiliary data message carrying indication information to the terminal.
[0162] In one embodiment, the LPP location information request message carries the identification information of the base station used for terminal positioning.
[0163] In one embodiment, the LPP provides auxiliary data messages carrying identification information of the base station used for terminal positioning.
[0164] In this way, by using the LPP to provide auxiliary data messages or LPP to send instruction information, the message compatibility of the LPP to provide auxiliary data messages is improved.
[0165] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0166] like Figure 8 As shown, this embodiment provides a wireless communication method, which is applied to a terminal. The method includes:
[0167] Step 81: Receive the indication information sent by the communication node;
[0168] The indication information is used by the terminal to determine the sending operation of the on-demand PRS request.
[0169] In some embodiments, the terminal may be, but is not limited to, a mobile phone, a wearable device, an in-vehicle terminal, a roadside unit (RSU), a smart home terminal, and an industrial sensing device.
[0170] In one embodiment, the communication node can be a base station.
[0171] This base station is an interface device for terminals to access the network.
[0172] In some embodiments, the base station can be various types of base stations, such as 3G network base stations, 4G network base stations, 5G network base stations or other evolved base stations.
[0173] In one embodiment, the communication node can be a functional network element in the core network.
[0174] Here, the functional network element can be AMF, SMF, and UPF, etc.
[0175] In one embodiment, the communication node is an LMF.
[0176] In one embodiment, when locating terminal A, base station B sends a PRS (Presentation Record) to terminal A. Upon receiving the PRS, terminal A measures it, for example, by measuring the RSTD (Real-Time Difference). Based on the measurement result, the distance to terminal A is determined.
[0177] Thus, based on the RSTD measured by terminal A, base station B can locate terminal A.
[0178] In one embodiment, the terminal needs to receive the PRS based on the PRS configuration. Therefore, the terminal needs to obtain the PRS configuration before receiving the PRS.
[0179] In some embodiments, PRS configuration includes PRS parameters such as period, bandwidth, and / or style.
[0180] In one embodiment, the terminal obtains the PRS configuration from the base station.
[0181] In one embodiment, the terminal sends an on-demand PRS request to the base station to obtain the PRS configuration. The terminal then receives the PRS configuration sent by the base station in response to the on-demand PRS request.
[0182] In one embodiment, in response to the terminal needing to send a PRS, the terminal sends an on-demand PRS request to the base station to obtain the PRS configuration.
[0183] In one embodiment, in response to the launch of a location application for locating the terminal, the terminal sends an on-demand PRS request to the base station to obtain the PRS configuration.

[0188] In one embodiment, determining the sending operation of an on-demand PRS request can be either that the terminal determines to send an on-demand PRS request to the base station or that the terminal determines not to send an on-demand PRS request to the base station.
[0189] In one embodiment, multiple TRPs are required to locate the terminal. Therefore, it may be necessary for the base stations corresponding to neighboring cells of the serving cell where the terminal is located to also participate in the terminal's location.
[0190] In one embodiment, the serving base station in response to the terminal includes multiple TRPs, the base station is able to determine the PRS configuration, and the indication information can instruct the base station to support the terminal in sending on-demand PRS requests to the base station.

[0192] In one embodiment, after receiving an instruction from the base station to support the terminal in sending an on-demand PRS request to the base station, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration.
[0193] In one embodiment, the pre-defined PRS configuration can be the current PRS configuration.
[0194] In one embodiment, in response to a failure to meet positioning requirements, the terminal sends an on-demand PRS request to the base station.
[0195] In one embodiment, in response to the predetermined PRS configuration not meeting the positioning requirements, the terminal sends an on-demand PRS request to the base station.
[0196] In one embodiment, failure to meet the positioning requirement may be due to the current base station not sending a PRS and / or the terminal lacking a PRS configuration available for receiving PRS. In one embodiment, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration, including:
[0197] In response to a PRS configuration that meets the requirements of the pre-defined PRS configuration, the terminal does not send an on-demand PRS request to the base station.
[0198] And / or,
[0199] In response to a PRS configuration that does not meet the required requirements, the terminal sends an on-demand PRS request to the base station.
[0200] In one embodiment, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0201] In one embodiment, in response to the base station not supporting the terminal sending on-demand PRS requests to the base station, the base station cannot determine the PRS configuration based on the on-demand PRS requests sent by the terminal.
[0202] In one embodiment, in response to the fact that the number of TRPs included in the serving base station of the terminal is less than the threshold number of TRPs required for positioning, neighboring base stations and the serving base station need to work together to locate the terminal.
[0203] In one embodiment, the serving base station needs to exchange information through the Xn interface between base stations to obtain the PRS configuration from neighboring base stations. In this case, the latency will be very long.
[0204] In one embodiment, in response to a base station needing to obtain PRS configuration from a neighboring base station, and the base station being unable to determine the PRS configuration on its own, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0205] In one embodiment, in response to the base station not supporting the terminal sending on-demand PRS requests to the base station, the terminal does not send on-demand PRS requests to the base station.
[0206] In one embodiment, in response to the base station not supporting the terminal sending an on-demand PRS request to the base station, the terminal sends an on-demand PRS request to the LMF and obtains the PRS configuration from the LMF.
[0207] In one embodiment, after receiving an indication that the base station does not support the terminal sending on-demand PRS requests to the base station, the terminal determines whether to send on-demand PRS requests to the LMF based on a predetermined PRS configuration.
[0208] In one embodiment, the predetermined PRS configuration is the initial PRS configuration.
[0209] In one embodiment, determining the sending operation of the on-demand PRS request can be either that the terminal determines to send the on-demand PRS request to the LMF or that the terminal determines not to send the on-demand PRS request to the LMF.
[0210] In one embodiment, the terminal determines whether to send an on-demand PRS request to the base station based on a predetermined PRS configuration, including:
[0211] In response to a PRS configuration that meets the requirements of the pre-defined PRS configuration, the terminal does not send an on-demand PRS request to the LMF.
[0212] And / or,

[0214] In one embodiment, the base station sends PRS configuration to the terminal via RRC messages.
[0215] In one embodiment, the LMF sends the PRS configuration to the terminal via an LPP message.
[0216] In one embodiment, the terminal can determine whether to send an on-demand PRS based on the received indication information. Compared with sending an on-demand PRS request without indication information, this can reduce the possibility of failure when the peer cannot provide PRS configuration, thereby reducing the latency of obtaining PRS configuration, reducing the time for locating the terminal, enabling rapid location of the terminal, and improving the user experience.
[0217] In one embodiment, the indication information includes one of the following:
[0218] The first piece of information instructs the base station to support the terminal in sending on-demand PRS requests to the base station.
[0219] The second piece of information indicates that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0220] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.
[0221] like Figure 9 As shown, this embodiment provides a wireless communication method, which is applied to a terminal. The method includes:
[0222] Step 91: Receive a system message carrying the indication information sent by the base station;
[0223] or,
[0224] During the random access process, the base station sends an MSG2 carrying the indication information.
[0225] or,
[0226] During the random access process, the base station sends an MSG4 containing the indication information.
[0227] or,
[0228] Receive the RRC message carrying the indication information sent by the base station;
[0229] or,
[0230] Receive a MAC message carrying the indication information sent by the base station;
[0231] or,
[0232] Receive the DCI message carrying the indication information sent by the base station.
[0233] In one embodiment, the system message may be SIB1 or the location SIB.
[0234] In this way, the instruction information can be carried in system messages, second messages, fourth messages, RRC messages, MAC messages, or DCI messages, improving the message compatibility of the above messages.
[0235] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0238] In one embodiment, in response to the fact that the number of TRPs included in the serving base station of the terminal is less than the threshold number of TRPs required for positioning, neighboring base stations need to work together with the serving base station to locate the terminal.
[0239] In one embodiment, the serving base station needs to exchange information through the Xn interface between base stations to obtain the PRS configuration from neighboring base stations. In this case, the latency will be very long.
[0240] In one embodiment, in response to a base station needing to obtain PRS configuration from a neighboring base station, and the base station being unable to provide PRS configuration on its own, the indication information may indicate that the base station does not support the terminal sending on-demand PRS requests to the base station.
[0241] In one embodiment, after the terminal sends an on-demand PRS request to the base station, it receives a second message from the base station indicating that the base station does not support the terminal sending an on-demand PRS request to the base station.
[0242] In one embodiment, in response to the base station having the ability to determine the PRS configuration requested by the on-demand PRS request (i.e., the base station can determine the PRS configuration individually) but the base station cannot meet the needs of multiple terminals requesting multiple different PRS configurations, a second message is sent for the on-demand PRS request.
[0243] For example, if multiple terminals simultaneously send on-demand PRS requests to the base station, and the PRS configurations requested in the PRS requests are not the same, then the base station cannot satisfy all the on-demand PRS requests of all terminals at the same time. Therefore, it can only send second information to the terminals for the on-demand PRS requests.
[0244] Here, indication information can be sent using RRC, MAC, or DCI instead of system messages.
[0245] It should be noted that those skilled in the art will understand that the methods provided in the embodiments of this disclosure can be executed alone or together with some methods in the embodiments of this disclosure or some methods in related technologies.

[0250] In one embodiment, the LPP location information request message carries the identification information of the base station used for terminal positioning.

[0252] In this way, by using the LPP to provide auxiliary data messages or LPP to send instruction information, the message compatibility of the LPP to provide auxiliary data messages is improved.

[0269] In response to a PRS configuration that meets the requirements of the pre-defined PRS configuration, the terminal does not send an on-demand PRS request to the base station.
